To all whom it' may concern:

Be it known that l, FRANK M; Bnoons, a citizen of the United States, residing in the borough of Brooklyn, in the county of Kings,

e city and State of New York, have invented an Improvement in Lighting-Fixtures, of

which the following is a specification.

My present invention relates to lighting ixtures and moreparticularly to the parts forming the clamping or gripping member, by which the bowl or globe is secured in position in the fixture.

Trieretofore, in lightinglixtures, the bowl or globe has been supported and maintained l5 in position in various manners by devices making a substantially unyielding gripping engagement or connectionv with the rimoi` the bowl or globe. F or example, in some 1nstances, the. rim of the bowl or globe has been employed to maintain the bowl or i globe inv position. In other cases, the supporting member or clamp has been provided with a pin adapted to pass through an aperbowl or globe, which pin, within the bowl, is provided with a nut, or other similar device, adapted to be turned down' against the inner surface of the rim to secure the parts in l) place.A In these, and all similar constructions, the connection between the hanger or support in the bowl or globe is, asV hereinbefore stated, substantially unyielding, and consequently the parts have to `be adjusted to 'position with much care, in order to allow for the expansion and contraction of the v bowl or globe, due to the different temperatures to which it is subjected. I am also aware that in lighting fixtures, there have been employed clamp members provided with yielding devices to ,engage the inner surface of the rim of the bowl, as for eX- ample, as shown and described in Letters Patent No. 1,115,166, granted to me October 27, 1914, for a lighting liXture hook. ,Even in the use of these yieldingly engaging hooks, however, some care is-also necessary. in adjusting the parts to position, and furthermore, when placed, the yielding member is in direct contact with the surface of the bowl, as is the cas'e with the clamps which are entirely unyielding in their nature. Furthermore, in all such cases, it is necessary to adjust the parts to position after the bowl 5 or globe is set in place inthe fixture.

been set within a ring, and set screws have ture provided therefor in the rim of the.

Now the object of my present invention is the provision, in a lighting xture, of a contheir permanent positions before the globe is set in place, the parts being so constructed that the engaging members of the lfixture are yielding and may be applied to the bowl so that, when in place, these yielding parts return to their normal positions andY retain the bowl and globe in' position, as will be hereinafter more particularly described.

In the drawing, Figure lis an elevation and partial section of a lightingiixture em bodying my present invention. Fig. 2 is a sectional plan of the same. Fig. 3 is an enlarged perspective view illustrating one of the cla-mp or gripping members. Fig. el is an elevation showing the inner side of one of the clamp members, and Fig. 5 is an elevation and partial section of the end of one of the hanger rods or support arms.

Referring more particularly to the draw ing, in carrying out my invention, I employ a'base or socket member 10, to which are suitably connected depending arms or hangers 11. It will be understood, however, that while I have illustrated a ceiling iXture, the invention hereinafter described is equally applicable to side wall, or other fixtures, and

also, while I have illustrated the depending members or support arms 11 as tubular, that a chain or other similar mea-ns, which arev sometimes employed, may be used without departing from the nature and spirit of my invention. i

At the lower extremity of each depending member 11 is an -end member' 12. On one side, each end member 12 is proviched with a lug 13, and at its diametrically opposite side with a lug 14. The lug 13 is preferably rectangular in cross section, and centrally is provided with a tapped recess 15. The lug 14 may be of any configuration in cross section, and adjacent its extremity is provided with a tapped aperture 16. A

clamp or gripping member,` adapted to eny gage the outer surfac'e'of the rim of the'v bowl, is indicated at 17. This is provided, in a suitableposition, with a boss 18, notched as indicated vat 19', to fit over the lug 13, and also apertured at 20, in order that the screw 21 may/be passed through the boss 18 and turned/down into the tapped' opening in the lug i3 'to secure the clamp i7 in position relativeiy to the lu fis will be understood, tbe clump membe" ifi' may be et' :my suitable design, iuoiieiiug portions thereof are uieotecl 'to engage the concave oi other e surface of the rim of tire bowl or Q23, is eleely iliustiateii in .l et" the ii-swing. also employ e ring i suitable resilient'meteiisl, siici siiisptecl in spaced positions, tlepencliiig the number of hangers employed, te seeue. to the lugs lle by means of scifews 'through epeitui'es piovio'lecl eie'foi iii the ring and tuiiiecl clown iut@ f e tapped. apeituies i6 eljeceut the es*-` ties ef the ings 1 i Also, es is eieaily iii isst ci in the chewing, the iugs i3 enti .positioned tliet when iu the Wiii nerim-lily essume posities efggiieeieble distance from the iiiee of the rim 22 of 'the bowl ieetecl in 2, :i bui'uei Aupleyeei iu tile iiglitioe' iixtuie, in 'i tie depeiioiiig; msnm is utilised. e ,ges pipe, but, es Wiii uIideistOGi, s suitable eleetiie iight fitmey also be usedV instead eii the gas 'uiiiei es illusti'ated.
